If i‘m not mistaken, then this is not possibile. You should set each Variable individually.

Correction: As jeremydouglass said below, it is actually valid code.

Actually, it is possible. Not always recommended, but valid code.

@somedude:

If you look at your error box, you will see that the error gives a line number: 40. If you click on the error message it will highlight the error line.

if (key =='LEFT') {

…you can’t put a String in single quotes in Java – it needs to be a char or Character, like ‘L’, or a String in double quotes like “LEFT”. But you don’t want either of those – you want the built-in PConstants keyword LEFT, which is a variable name and so doesn’t appear in quotes at all.

…AND you want to use it like this:

color fillVal = color(126);

void draw() {
  fill(fillVal);
  rect(25, 25, 50, 50);
}

void keyPressed() {
  if (key == CODED) {
    if (keyCode == LEFT) {
      fillVal = 255;
    } else if (keyCode == RIGHT) {
      fillVal = 0;
    } 
  } else {
    fillVal = 126;
  }
}
